Abstract: 1,201,430. Control of A.C. motors. BROWN BOVERI & CO. Ltd. 23 Oct., 1968 [25 Oct., 1967], No. 50239/68. Heading H2J. An A.C. motor 1 which is energized via electronically controlled switches (thyristors) 9, 10 and 11, 12 is braked by the switching on of a controlled rectifier (thyristor) 13 for a predetermined time following the cessation of control signals for the switches 9 . . . 12. As shown, the motor is a single phase induction motor having two windings 4, 5 and a phase splitting capacitor 17, and it runs in either direction according to whether 9, 10 or 11, 12 are triggered, which is determined by the polarity of a control voltage at 22. When this voltage is above a given threshold an amplifier 19 or 21, according to polarity, energizes a relay 18 or 20 which applies triggering voltages to 9, 10 or 11, 12. The output of a further amplifier 27 holds a pulse generator 28 quiescent but when the output of 19 or 21, and hence 27, becomes zero a single pulse of predetermined duration energizes a further relay 29 which applies triggering voltages to braking thyristor 13 for that time. A resistor 14 may limit the braking current. The motor may vary the pitch of a ship's propeller and it is stated that it could alternatively be a three phase synchronous machine.

Abstract: 1459886 Cooling brakes DAIMLER-BENZ AG 29 Nov 1974 [1 Dec 1973] 51861/74 Heading F2E In a motor vehicle having a change-speed gear-box and including a braking system comprising a sustained-action brake in addition to the wheel brakes, the sustained-action brake 11 is arranged on the output shaft 10 of the gearbox and comprises a multiple-disc full-face brake operated at 18, 17, by a fluid medium and having a coolant circulating circuit 45, 30, 12, 14, 30, 48 the operation of which is a function of the position of the service brake pedal 20, the cooling circuit including a heat exchanger 36 and being fed by a controllable pump 22 driven by the vehicle driving engine. The pump 22 also supplies servo-steering gear 26 (via throttle 25), the gear-box and its servo (via valve 31) and the motor 40 of a cooling fan 39 for heat exchanger 36. Pedal 20 operates a switching valve 41 (which when in the position shown establishes flow in the coolant circuit) and, via spring 21, an operating valve 19 which regulates the pressure in the circuit. A valve 29 responsive to the water temperature in heat exchanger 36 determines whether oil from pump 22 passes to the heat exchanger directly or via the fan motor 40. If the oil temperature at the heat exchanger outlet is too high, a valve 33 establishes flow through a circuit 49, 35, 34 to increase the pump capacity. The gear-box may be epicyclic and have servo-shift means, a gear ratio controlling element of the gear-box not required for gear shifting being used as the sustained-action brake.

Hot compressed air entering through an inlet 12 flows upwardly into a cupshaped baffle 16 defined by a cylindrical wall 18, a top plate 20 and an apertured bottom closure member 22. Air, after entering and leaving the baffle interior via the apertures 24, then flows upwardly through an annular space 34 between the wall 18 and the casing 7 and thereafter through the filter unit 40 before finally leaving via an outlet 56. The filter unit 40, which comprises filter material 50, e.g. stainless steel wool located between upper and lower perforated plates 42, 46, is normally spring urged downwardly against a washer 38 by means of a coil spring 41. If however, during operation, the filter material becomes choked with dust and carbon particles the pressure of the air will force the filter 40 upwardly against the spring 41 thereby allowing air to pass to the outlet 56 via an annular space 48 surrounding the filter unit. A pneumatically operated valve 58 is provided to permit, by purging, removal of water, oil and carbon particles from the annular passage 34 through a drain opening 62. All materials used in the interior of the cooling section 4 are non- ferromagnetic to prevent the likelihood of clogging due to sticking of magnetized particles.
